Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, specifically to a high-strength brake caliper. Background Technology

[0002] Brake calipers are a key component of a car's braking system. Their main function is to clamp the brake pads, causing them to rub against the brake disc, thereby reducing the wheel speed and achieving vehicle braking.

[0003] A search revealed that patent application CN202421749804.7 discloses a brake caliper that reduces caliper size by placing gear sets and other components on the outside of the nut. While this device improves structural compactness through innovative layout, its overall structure is relatively complex. Precise control of the installation position and dimensions of multiple components is required during manufacturing, making it challenging. Furthermore, the fit between components is significantly affected by manufacturing errors during assembly, easily leading to assembly deviations and unstable braking performance. Additionally, due to its high degree of integration, disassembly and reassembly are cumbersome and maintenance is difficult when key components such as the piston rod and seals malfunction, hindering rapid repair and replacement and impacting the practicality and reliability of the brake caliper. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-strength brake caliper that solves the problems mentioned in the background section.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A high-strength brake caliper includes a caliper body, wherein the caliper body is provided with an oil return port and an oil inlet port;

[0007] The caliper body has a mounting groove on one side, which is connected by a connecting hole. The oil inlet has a flow channel, which is connected to the oil return port and the mounting groove through the flow channel. The caliper body has a mounting hole, and an end cap is mounted on the caliper body through the mounting hole. The end cap has a sealing edge and a second sealing groove, and the end cap is sealed and connected to the mounting hole through the sealing edge and the second sealing groove.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the caliper body is provided with heat dissipation holes to assist in cooling the brake disc.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The placement of cooling vents significantly improves the heat dissipation efficiency of the braking system. When the brake disc generates high temperatures due to friction during braking, the cooling vents guide airflow directly through the caliper body, accelerating heat dissipation and effectively reducing the temperature of the brake disc and brake pads. This not only inhibits brake performance degradation caused by high temperatures and extends the lifespan of the brake pads, but also prevents hydraulic oil from vaporizing due to overheating, ensuring the stability and reliability of the braking system.

[0012] Furthermore, the caliper body is provided with fixing holes, through which the caliper body is installed and fixed.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The mounting hole design provides a precise and secure mounting method for the caliper body. Secure the caliper to the vehicle's suspension system via bolts or other fasteners passing through the mounting holes, ensuring the caliper maintains a precise position during braking and preventing displacement or vibration due to uneven force. This rigid connection not only improves the directness of braking response but also reduces noise and wear caused by caliper wobble, extending the overall lifespan of the caliper. Furthermore, the standardized mounting hole design facilitates caliper replacement and maintenance, reducing maintenance costs.

[0015] Furthermore, a mounting groove is formed in the mounting hole by the end cap, and a first sealing groove is provided at the opening of the mounting groove of the caliper body.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The fit between the end cap and the mounting hole forms a closed mounting groove structure, providing a stable working environment for the piston rod and hydraulic system. The opening of the first sealing groove allows for the installation of a high-precision sealing ring, effectively preventing hydraulic oil leakage. This dual-sealing design not only maintains stable pressure in the hydraulic system but also prevents external dust, moisture, and corrosive media from entering the caliper, protecting the piston rod and other critical components from corrosion, thereby improving the reliability and durability of the braking system, and is especially suitable for harsh working environments.

[0018] Furthermore, a piston rod is installed in the mounting groove, which is used to push the brake pads to contact the brake disc. A sealing ring is installed in the first sealing groove, and the mounting groove and the piston rod are sealed by the sealing ring.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] As the actuator that directly pushes the brake pads, the precise seal between the piston rod and its mounting groove is crucial. The use of a sealing ring ensures that hydraulic oil does not leak from the gap between the piston rod and the mounting groove, thus allowing hydraulic energy to be fully converted into mechanical energy to push the piston rod, improving braking efficiency. Simultaneously, the sealing ring also serves to prevent dust and lubricate, reducing frictional resistance during piston rod movement, minimizing wear, and extending the piston rod's service life. Furthermore, this sealing structure prevents debris generated during braking from entering the hydraulic system, avoiding system malfunctions.

[0021] Furthermore, the piston rod within the mounting groove is driven by hydraulic oil within the mounting groove.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] Hydraulic drive offers advantages such as smooth transmission, rapid response, and uniform force distribution. When the driver depresses the brake pedal, hydraulic oil enters the mounting groove under the action of the master cylinder, pushing the piston rod in a linear motion, causing the brake pads to quickly engage with the brake disc. Compared to mechanical transmission, hydraulic drive eliminates the need for complex lever mechanisms, reducing transmission backlash and energy loss. It can more directly amplify and transmit the driver's operating force to the braking system, achieving precise control. Furthermore, the hydraulic system can easily distribute and adjust braking force by rationally designing the flow channels and piston area, adapting to different braking needs.

[0024] This invention provides a high-strength brake caliper. It has the following advantages:

[0025] The end cap is sealed to the mounting hole through the sealing edge and the second sealing groove. At the same time, the first sealing groove at the opening of the mounting groove has a built-in sealing ring, forming a double sealing structure, which effectively prevents hydraulic oil leakage, ensures stable braking system pressure, and improves braking reliability.

[0026] The oil inlet is connected to the oil return port and mounting groove via a flow channel, and the internal oil circuit is integrally formed, reducing the number of external pipeline interfaces. This reduces the risk of interface leakage, simplifies the assembly process, and at the same time, the low hydraulic oil flow resistance improves the oil circuit response speed.

[0027] By first precisely drilling mounting holes, then machining mounting grooves based on these holes, and finally forming a cavity through the sealing fit between the end cap and the mounting holes, this solution not only reduces machining difficulty and improves the assembly accuracy of the mounting groove and other components, but also enables convenient disassembly and maintenance of key components such as piston rods and sealing rings through modular design. This effectively solves problems such as complex machining, low assembly accuracy, and difficult maintenance in existing technologies, significantly improving the practicality and reliability of brake calipers.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1: A high-strength brake caliper includes a caliper body 1. The caliper body 1 has an oil return port 103 and an oil inlet port 104. One side of the caliper body 1 has a mounting groove 108, which is connected to the caliper body 1 through a connecting hole 109. The oil inlet port 104 has a flow channel 102, which is connected to the oil return port 103 and the mounting groove 108 through the flow channel 102. The caliper body 1 has a mounting hole 106, and an end cap 2 is mounted on the caliper body 1 through the mounting hole 106. The end cap 2 has a sealing edge 201 and a second sealing groove 202, and the end cap 2 is sealed and connected to the mounting hole 106 through the sealing edge 201 and the second sealing groove 202.

[0040] Example 2: To improve the heat dissipation performance and installation stability of the braking system, for example, such as Figures 1 to 5 As shown, this utility model also includes: a heat dissipation hole 101 on the caliper body 1, which assists in cooling the brake disc, significantly improving the heat dissipation efficiency of the braking system. When the brake disc generates high temperatures due to friction during braking, the heat dissipation hole 101 guides airflow directly through the caliper body 1, accelerating heat dissipation and effectively reducing the temperature of the brake disc and brake pads. This not only inhibits brake performance degradation caused by high temperatures and extends the service life of brake pads, but also prevents hydraulic oil from vaporizing due to overheating, ensuring the stability and reliability of the braking system. The caliper body 1 is provided with a fixing hole 105, through which the caliper body 1 is installed and fixed. The design of the fixing hole 105 provides a precise and stable installation method for the caliper body 1. By fixing the caliper to the vehicle suspension system with bolts or other fasteners through the fixing hole 105, it is ensured that the caliper maintains a precise position during braking, avoiding displacement or vibration due to uneven force. This rigid connection not only improves the directness of braking response but also reduces noise and wear caused by caliper wobble, extending the overall lifespan of the caliper. Furthermore, the standardized mounting hole 105 design facilitates caliper replacement and maintenance, reducing maintenance costs.

[0041] Example 3: To enhance the sealing performance and transmission efficiency of the braking system, for example, such as Figures 1 to 5As shown, this utility model also includes: a mounting groove 108 formed within the mounting hole 106 by the end cap 2, and a first sealing groove 107 is provided at the opening of the mounting groove 108 of the caliper body 1. The cooperation between the end cap 2 and the mounting hole 106 forms a closed mounting groove 108 structure, providing a stable working environment for the piston rod and hydraulic system. The opening of the first sealing groove 107 allows for the installation of a high-precision sealing ring, effectively preventing hydraulic oil leakage. This double sealing design not only maintains the pressure stability of the hydraulic system, but also prevents external dust, moisture, and corrosive media from entering the caliper, protecting the piston rod and other key components from corrosion, thereby improving the reliability and durability of the braking system, especially suitable for harsh working environments. A piston rod is installed in the mounting groove 108, which is used to push the brake pads to contact the brake disc. A sealing ring is installed in the first sealing groove 107, and the mounting groove 108 and the piston rod are sealed by the sealing ring. As the actuator that directly pushes the brake pads, the precision seal between the piston rod and the mounting groove 108 is crucial. The use of a sealing ring ensures that hydraulic oil does not leak from the gap between the piston rod and the mounting groove 108, thus allowing hydraulic energy to be fully converted into mechanical energy to drive the piston rod, improving braking efficiency. Simultaneously, the sealing ring also serves as a dustproof and lubricant, reducing frictional resistance during piston rod movement, reducing wear, and extending the piston rod's service life. Furthermore, this sealing structure prevents debris generated during braking from entering the hydraulic system, avoiding system malfunctions. The piston rod within the mounting groove 108 is driven by hydraulic oil within the groove. Hydraulic drive offers advantages such as smooth transmission, rapid response, and uniform force transmission. When the driver depresses the brake pedal, hydraulic oil enters the mounting groove 108 under the action of the master cylinder, pushing the piston rod in a linear motion, causing the brake pads to quickly engage with the brake disc. Compared to mechanical transmission, hydraulic drive eliminates the need for complex lever mechanisms, reducing transmission gaps and energy loss, and more directly amplifying and transmitting the driver's operating force to the braking components, achieving precise control. Moreover, the hydraulic system can easily distribute and adjust braking force by rationally designing the flow channel 102 and piston area, adapting to different braking needs.

[0042] Working principle:

[0043] First, the mounting hole 106 is precisely drilled, and the mounting groove 108 is machined based on this. This machining method reduces the difficulty of individually positioning and machining the mounting groove 108 during the manufacturing process, and reduces the accumulation of errors. Then, the end cap 2 is installed on the mounting hole 106 through a sealing fit, forming a closed cavity, providing a high-precision foundation for the subsequent installation of core components. Because the machining precision of the mounting groove 108 is guaranteed, higher assembly precision can be achieved when installing components such as the piston rod and sealing ring, resulting in a tighter fit between components and reducing braking performance loss due to assembly errors.

[0044] When the driver depresses the brake pedal, brake fluid enters the sealed cavity formed by the mounting hole 106, end cap 2, and mounting groove 108 through the inlet 104. Thanks to high-precision assembly, the seal between the piston rod and the mounting groove 108 effectively seals the space, ensuring efficient transmission of hydraulic energy. This pushes the piston rod out, which in turn causes the brake pads to clamp the brake disc, achieving braking. The high-precision assembly makes the braking force transmission more stable and uniform, improving braking performance.

[0045] Thanks to its modular design, when critical components such as the piston rod and seals wear out or malfunction and need replacement, only the end cap 2 needs to be removed for easy disassembly and maintenance of the internal components. Unlike traditional brake calipers, there is no need for complex overall disassembly and reassembly, which greatly shortens maintenance time, reduces maintenance difficulty, improves the practicality and reliability of brake calipers in actual use, and reduces vehicle downtime caused by brake caliper maintenance.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
